My thoughts exactly.

I’ve been wondering if perhaps the “new” rebar requirement in the Rohn catalogs is for _pier pin_ bases.  It seems to me that the total size of the foundation hole Rohn specifies for modest R25 and R45 guyed tower heights doesn’t leave much room for rebar when you plant a regular or short triangular section of R25 or R45 in the hole — especially if you need a minimum of 3” cover!
